@sam: Try changing the value of scalesPageToFit. Apple’s documentation has this to say about this attribute: “If YES, the webpage is scaled to fit and the user can zoom in and zoom out. If NO, user zooming is disabled. The default value is NO.”

I have the same problem as Ichy. I tried to post some code but my posts got pulled. Basically, I have a web page that is zoom-able in safari, I grab it’ html, put the html into a UIwebview, and the new web view isn’t zoom-able. Why is this? Everyone talks about it like its default behavior. Any help would be much appreciated.

Also, I tried many html chunks that zoom well in the iPhone safari and then copied them into this web view and they stopped zooming. No good!

I am having the same problem as Ichy and I can’t find anyone that understands. I put a UIWebView in by adding as a subview, then I do a loadHtlm, and there is no zoom going on! I wrote out my problem in a zip file. It has the h and m files. please let me know anyone can fix the zoom on this and what the solution is. Any help would be appreciated as this is holding up a project of mine and could kill it entirely if I can’t find a solution. The zip is at http://www.timewalksoftware.com/files/NoZoomWebView.zip

- Thanks,
Sam

@pramod: There seems to be a lot of confusion surrounding UIWebView and caching on the iPhone. I have not done any testing myself so unfortunately I cannot add any clarity. But this Stack Overflow entry seems to have the best overview of the situation.

Does UIWebView cache the images loaded using img src tag. if so where do it cache in the iPhone and what is the time it keeps its content into its cache.

@Icky: That should work. It could be an HTML error. Try to load the same HTML in Safari on your iPhone and see if you can zoom the image.

I actually have sort of the opposite problem: I cannot zoom. I add a UIWebView as a Subview to my main View and load an image within. The image is shown, I set setScalesPageToFit to YES, this should allow me too zoom – so it says.

Any ideas on what I could be missing?

I would really appreciate it!

@ashish: You might try changing the HTML width and height attributes of the images.

Hi Nick,

How to change image size, width and height in UIWebView.

suppose the html file contains images with different size I want those images to fit inside the UiWebView.

I am not using [mywebView setScalesPageToFit:YES]; because it allows user to zoom.

Any other way to resize Images before loading into Webview might be using java script?
